Lithography is only just beginning to play a role in cell IP selection but early analysis already matters.
A look at the way in which key tools, in IC implementation, modeling and extraction, and physical verification, are developing in response to the challenges of 20nm design
By the time a serious lithography-related problem is identified at the fab, it is too late in the design process to make simple layout changes. To avoid or reduce design delays, Infineon Technologies uses lithography simulation to detect weak points in a layout and analyze the effect of lithography on the design’s electrical performance. Its [...]
DRC+ is a new methodology that algorithmically characterizes design variation through pattern classification. A traditional design rule is used to identify all design structures that share a common configuration. Then, the 2D geometric situations (pattern variations) around the configuration are extracted and classified. Since all such classes share a common configuration, each situation class represents [...]
DFM is essential to differentiating your products in the market, says Luigi Capodieci
Design for manufacturing (DFM) sign-off is a required step in most deep sub-micron technology design environments. However, there is no common methodology for DFM sign-off. We believe DFM should not only give an estimate of the yield, but should also point out where failures are most likely to occur, and where designers can improve their […]
